N-Heterocyclic Carbenes

Carbonyls

1. Carbonyl complexes are favorably formed with low valent metal centers.
2. The number of carbonyl bands in the IR spectrum is indicative of the number of CO ligands in the complex.
3. Homoleptic carbonyl complexes exhibit only one CO band.
4. Homoleptic carbonyl complexes exhibit only one CO band.
5. Coordination of a carbonyl ligand to a low valent metal generally leads to...
6. Reduction of a metal-carbonyl complex generally leads to...
7. Nucleophilic attack of a bound carbonyl occurs at...
8. What does the Tolman Electronic Parameter measure?
